3 Claims.

This invention relates to methods of preserving razor blades and of depositing them upon safety razors and to means for carrying out these methods.

This patent application is a continuation in part of my co-pending patent applications, led, respectively, April l, 1936, Serial No. 72,068 and September 4, 1936, Serial No. 99,380.

Safety razor blades are now packed individually in oiled paper and are enclosed in a paper envelope. Five, ten, or a larger number of such envelopes are packed together in packages made of heavier paper or of cardboard.

Past experience has shown that this method of wrapping razor blades does not prevent the sharp edges thereof from rubbing against the paper wrapping, so that often the ends become dull before the user removes the razor blade from its wrapping for the rst time.

At the present time, the removal of the razor blades from their Wrappings and the placing of such razor blades upon safety razors is carried out by hand. The user must rst open the paper envelope to produce the razor blade Wrapped in oiled paper, then remove the oiled paper, and holding the razor blade in one hand, place it upon the safety razor, which is held inl the other hand.

Everyday experience shows that the fingers or the hands of the user are frequentlycut by the sharp edges of the razor blade when the blade is unwrapped and placed upon the safety razor. Furthermore, the form of the blade prevents the usertfrom holding it securely, with the result that the blade is often dropped and damaged. It is extremely inconvenient and dangerous to pick up a dropped blade when it lies upon a flat surface.

An object of the present invention is the provision of methods of removing a blade from its package and depositing it in its proper position upon a safety razor without any contact with the hands or the fingers of the user, thereby eliminating the danger of injury to the user.

Another object is the provision of blade supporting means which will eiectively protect the sharp edges of the blades not only while the latter are not in use but also While they are being unwrapped and placed upon the safety razors.

The above and other objects of the present invention may be realized through the provision of methods of transporting a blade which consist in securing a single blade by any suitable means upon a single supporting surface; the blade remains secured to this surface while it is being shipped, sold to a consumer, and kept by him prior to use. When it is desired to use the blade, the supporting (Cl. 20G-46) surface is moved by the user to the required position adjacent the safety razor, and then the blade is freed from the safety razor, in any one of the following ways:

First, the supporting surface may be bent rela 5 tively to the blade, thereby freeing the blade and causing it to drop upon the safety razor.

Secondly, the supporting surface may be bent along with the blade until the means holding the blade upon the supporting surface frees the blade and causes it to drop upon the safety razor.

Thirdly, the blade may be moved or bent by any suitable means relatively to the supporting surface and thereby freed from engagement with said supporting surface.

Fourthly, the support, or a part thereof, may be moved sidewise relatively to the blade in the direction of the cutting edge thereof, thereby freeing the blade and placing it in the proper position upon the safety razor. 9

Fifthly, the blade may be drawn away from its support and deposited upon the razor by magnetic attraction, suction or the like.

Finally, the support and the blade may be separated from each other by a twisting or turning mo- 20 tion of one of these elements relatively to the other.

Several constructions may be used for carrying out these methods of separating the blade from its support, some of these constructions being shown by way of example only in the accompanying drawingawherein Figure 1 is a perspective view of a support carrying a blade;

'I'he safety razor blades used in connection with the present invention may be of any standard form, although in certain instances it is preferred to employ blades provided with two sharp cutting edges and two tongue portions formed by the dull edges of the blade and separated by shoulders from the cutting edges.

The blade supports manufactured in accordance with the present invention may be made of cardboard or of any other suitable fibrous and/or flexible material. In other instances, the supports should preferably be made of a hard, resilient material, such as metal, or metal alloy for example, steel or the like. 'I'he supports should be wider than the blade, in order to protect its edges as well as the fingers of the user.

'I'he surfaces of the blade support are preferably water-proofed and rust-proofed by waxing or by any other appropriate means.

The blade support 26 shown in Figures 1 and 2 is provided with flaps or bent-over portions 2| and 22, which have cut-out portions 23 and 24, respectively. The tongue ends 25 of a blade 26 pass through the openings 23 and 24 and fit snugly into these openings, so that any shifting of the blade 26 upon the support 26 is prevented.

The middle portion of the support 26 is preferably provided wtih two parallel ridges 21 and 28, so that the blade 26 rests upon these ridges and not upon the flat surface of the support. The flap 2| is provided with similar parallel ridges 29, While the ap 22 is provided with parallel ridges 36. By this arrangement the blade 26 is conveniently supported without contacting the entire surface oi' the support (Fig. 2).

T'he support 46 shown in Figures 3 and 4 comprises a middle portion provided with four projections or bulging portions 4|, 42, 43 and 44. 'Ihese projections are so located that when a blade 26 is placed upon the support, the two pairs of bulging portions will t snuglv between the two tongue ends 25 of the blade 26, thereby maintaining the blade 26 in its position upon the support 46 and preventing any shifting thereof.

'I'he support 46 comprises two flaps 45 and 46. The flap 45 is provided with two recessed portions 41 and 46 fitting over the projections 4| and 42, respectively. The flap 46 is provided with similar recessed portions 49 and 56 fitting over the projections 43 and 44, respectively. 'Ihe flaps may be provided with ridges if desired.

In both constructions, the blades carried by the supports are freed by bending or moving the supand then the support 26 is removed, leaving the blade in its proper position.

The same support can be used for picking the blade on' the razor after use, whereupon the blade carried by the support may be discarded, or it may be preserved for subsequent use.

The support 40 (Figs. 3, 4, and 5) is used in a substantially similar manner, namely, the blade 26 is placed upon the razor by first opening one of the flaps 45 and 46, placing the freed end of the blade upon the safety razor, and then removing the support.

Figures 6 and 7 illustrate a support which frees the blade carried thereby by relative sidewise sliding movements oi' the support. y

The blade 26 is situated between two sheets or leaves 66 and 6|. 'I'he two leaves 66 and 6| may be made of one piece and connected with each other by the edge portion 62.

As shown more clearly in Figure 1, only a portion of the blade 26 is enclosed between the sheets 60 and 6|, the remaining portion of the blade projecting beyond these members. `This projecting portion is enclosed between two leaves or sheets 63 and 64, which are interconnected by the edge portion 65 and which overlap the leaves 60 and 6|,

'I'he lower'. supporting sheet 63 is provided with two projections 14, only one of which is shown in the drawings, and which are used to hold the left-hand tongue portion 25 of the blade 26 (looking in the direction of Fig. 7). The supporting sheet 66 is provided with a. similar pair of projections 66 used for holding the right-hand tongue portion 25 of the blade 26.

The upper leaf 6| is also provided with two recessed portions 61 into which fit the projections 66 provided upon the leaf 66. Two recessed portions 69 are formed on the leaf 64 opposite the projections 14.

Two pairs of projections 66 and 16 constituting parts of the leaves 63 and 64 fit into recessed portions 12 and 13 formed in the leaves 66 and 6 l, respectively.

The sheets 66, 6|, 63, and 64 may be provided with a central opening 1| which is somewhat larger than the central opening of the blade 26.

A support of this type may be provided with suitable ridges supporting and/or engaging the razor blade.

In this case; the blade 26 is removed from its support, first by pulling the leaves 63 and 64 away from the leaves 66 and 6| in the direction of the axis 1-1. Due to this pulling movement, the projections 16 and 68 will snap out of the recessed portions 13 and 12, respectively, thereby freeing the leaves 63 and 64. After the removal of the overlapping portion 63, 64 of the support, a portion of the blade will be freed, so that it can be placed in its proper position upon the safety razor. Then the inner leaves 66, and 6| are removed by a sidewise sliding motion, thereby freeing the blade entirely.

Another example of the freeing of the blade from the support by the sidewise sliding movement of one part of the support relatively to the other is illustrated in Figures 8, 9 and l0 of the drawings. 'I'he support shown in these figures comprises a tray 86 having upturned flanges 8| and four projections 62 which are situated between the tongue ends 25 of a razor blade 26 and thereby hold the razor blade in position upon the tray 66, preventing any sidewise movement or longitudinal movements of the blade relatively to the tray.

The tray is enclosed by a cover 03 having flanges 84 which engage the flanges 8| and are slidable thereon. The cover 83 is also provided with a downwardly extending flange 85 which, in the closed position of the support, engages the edges of the flanges 8| thereby preventing any further movement of the cover 83 in the same direction. The cover 83 may also be provided with ridges 86 used for holding the blade in position.

In this case, the support while closed is turned over the guard of the razor blade, and then the cover 83 (and/or the tray 80) is removed by a sliding lengthwise movement, thereby causing the blade 26 to fall out of the tray 80 and to be deposited on the safety razor.

Figures 11, 12 and 13 illustrate the freeing of a blade by a turning or twisting movement. The support shown in these figures comprises a flat, substantially rectangular piece 90 provided with a comparatively large central opening 9| and having two hooks 92 and 93 which are situated on opposite sides of each other and which are adapted to engage the dull tongue end portions 25 of a blade 26. As shown in Figure 13, the blade is first placed with its support upon the safety razor and then the support is turned relatively to the blade in the direction of the arrow 94, whereby the hooks 92 and 93 will slide over the tongue portions 25 of the blade 26 and will free the blade, so that it will be safely deposited upon the razor.

The construction shown in Figures 14 and 15 illustrates the method of freeing the blade from the support by bending the blade relatively to its support. The blade 26 is carried by a support |00 and is held thereon by any suitable projections |0|. The support |00 is provided with a central opening |02 which extends to one of the side edges |03 of the support.

In addition to the projections |0|, the blade 26 is preferably held upon the support |00 by any suitable spots of adhesive |04.

In order to free the blade, the support |00 is first placed adjacent the razor, then the blade is held firmly either manually or by any suitable mechanical means, not shown in the drawings, while the support is moved in the direction of the cutting edge of the blade. During this movement the edges of the blade will gradually slide over the projections |0|, thereby bending, pushing or forcing the blade away from the support |00 until the bending force is suilicient to overcome the force of the adhesive |04 and liberate the blade entirely, which will then drop into its proper position upon the support.

The support ||0 shown in Figure 16 comprises four projections holding the blade 26, as well as overlapping portions ||2 extending over the tongue ends 25 of the blade 26. In order to drop the blade 26 upon the safety razor, the user must hold the support upside down over the razor and then bend the edges ||3 and ||4 of the support toward each other, thereby raising the portions ||2 which will then free the blade, so that the latter will drop upon the safety razor.

When the user has finished shaving himself with the blade, the support ||0 may be placed over the blade which is lying upon the razor, thereby protecting the edges of the blade and preventing the user from cutting himself with the sharp edges of the blade. Or, the support ||0 may be used for removing the blade from the safety razor, by means of the portions H2.

It is apparent that the specific illustrations shown above have been given by way of illustration and not by way of limitation and that the structures above described are subject to wide variation and modification without departing from the scope or intent of the invention, all of which variations and modifications are to be included within the scope of the present invention.
